I am incredibly attached to my fish. Whenever a betta passes on me, there is normally a good few days of mourning and all. That's actually how my boyfriend and I got so close. After our incredibly awful first date, I come back to my dorm and one of my rescues was dead. He stayed on the phone with me for five hours while I was in hysterics.
Even when one of my rainbows or danios jump, I get rather upset. I cry and am down all day. I had a bumble bee catfish that developed something bad and I was screaming and crying while I saw him suffer (put him down, of course).
I talk to my fish and have a pretty close connection. They all get lots of my time and energy. I would say I am very close to them. It is an obvious difference from how I am with my gecko. Although I can interact with him, he is not as aware of me as my fish are. Especially my flowerhorn. I almost feel like he talks to me.
Anyway, I'm going to be the crazy person who deals with fish deaths like they are humans. Guess that's why everyone calls me a crazy fish lady.
